With only 320 acres I would get a price in mind, maybe $6 or $7 per acre (you should be able to get the going rate in your area from a game warden) and offer it to a couple of hunters you know for the deer hunting, then you could get $2 or $3 per acre for the turkey hunting either from the same few people or different hunters. Let them be responsible for maintaining insurance and the expense of food plots. Keep the number of hunters as low as possible, it will be easier to manage. Be up front with your ideas about deer harvest, and if they don' t like it seek out other hunters. You could form a club, but it can be a real pain.
